Since you know the details, I think you'll appreciate this:
Debian uses the openboot firmware to directly fetch a
bootstrapping linux kernel image and root file system. The image
is about 2.3M, and the size is only limited by sparc memory,
since it's fetched by tftp. Bootp isn't involved, but some
things would be easier if it were. That's why I mentioned
"splitting hairs over sun's network boot sequence." The two
stage bootstrapping is not a NetBSD issue, it's a Sun issue,
which Debian (Ben Collins rolls the image) deals with their own
way.

I am a fan of netbooting and rescue, too. I know you're not
picking on me, because we're not talking about recursion in
scheme! By the way, you can write your shell scripts in scheme
now :-) :
